Yes. > I'm confused by the "Call-in" - "Call-out" terminology. I have an > external modem connected to 1st serial port, and I use it as > /dev/ttyd0. Does it mean it becomes a call-in device? The only real difference between the devices is that call-in devices block when you try to open them, and unblock when carrier is detected (i.e. if someone calls into the modem and it's set to auto-answer). When a process is blocked, another process can "steal" the port by opening the callout device, which doesn't block. It's described in the sio manpage, too. -- Dan Nelson [EMAIL PROTECTED] _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
